Integrated Interpretation and Simultaneous Joint Inversion of CSEM and Seismic Datasets - The Sunshine Case

We present an integrated workflow applied to re-image multi-client wide-azimuth seismic data acquired over 35 blocks in the Keathly Canyon/Walker Ridge area of the Gulf of Mexico. Seismic and EM data are utilized first in a cooperative workflow through localized seismic imaging reverse-time migration (LSI RTM) to validate new salt structures highlighted by single-domain 3D anisotropic CSEM and MT inversions. Simultaneous Joint Inversion (SJI) of EM and seismic data is used to update a multiproperty earth model by jointly minimizing the CSEM data misfit, the seismic residual moveouts, and a relationship between the properties.
